Scombroid fish poisoning, intentional self-harm, init encntr

This code signifies a patient presenting with symptoms of scombroid fish poisoning, such as flushing, headache, palpitations, and gastrointestinal upset, specifically when the poisoning is determined to be the result of a deliberate act of self-harm. The "initial encounter" indicates that this is the first time the patient is receiving active treatment for this specific poisoning episode.

Apply this code when documentation clearly states that a patient intentionally ingested scombroid-contaminated fish with the intent to harm themselves, and they are currently undergoing initial evaluation and management for the resulting toxic effects. This would be used in emergency department visits or initial inpatient admissions for such an event.

• Ensure physician documentation explicitly states "intentional self-harm" and "scombroid fish poisoning."
• Verify that this is indeed the initial encounter for this specific poisoning episode; subsequent care would use a different encounter character.
• Always code any associated mental health diagnoses (e.g., depression, suicidal ideation) in addition to this code.
